Abstract: Apparatus and method for Implementing a virtual display. For example, one embodiment of a graphics processing apparatus comprises host execution circuitry to execute instructions to implement a host and virtualization instructions to implement a virtualized execution environment comprising a plurality of virtual machines (VMs); graphics execution circuitry to execute graphics instructions to render framebuffers on behalf of each VM, each framebuffer associated with a virtual function (VF); and a display engine comprising one or more display pipes and a plurality of display planes; wherein a dynamic mapping is to be performed to associate one or more of the framebuffers to one or more of the display planes, the dynamic mapping comprising generating a framebuffer object with framebuffer information required by a physical function (PF) of the host to update the one or more display planes.
